Exploration of the principle of 6G communication technology and its development prospect

Nowadays, 5G has been widely used in various fields. People are starting to turn their attention to 6G. Therefore, at the beginning, this paper describes in detail the principle and performance of 6G, and introduces the key technologies of 6G, Cavity technology and THz technology. Based on the high-performance indicators of 6G, we then study the possible application changes brought by 6G, for example, 6G technology will make remote surgery and remote control possible. 6G technology will make remote surgery and remote control possible. 6G will speed up the interconnection of everything, allowing closer and faster connection between cars. Next, virtual reality is discussed. 6G technology will enable better development of virtual reality technology and enhance people's immersive experience. Finally, we present the issues that need to be addressed with 6G technology, such as cybersecurity issues and energy requirements. As well as the higher challenges facing 6G technology, such as connectivity and communication on a larger social plane.
